Applying the recursive formula to a geometric sequence

The video tutorial explains how to write the first four terms of a geometric sequence using a recursive formula. The instructor demonstrates the process by plugging in values to find each term sequentially, starting from the first term. The tutorial concludes with the calculation of the fourth term and a brief summary of the sequence.

What are the first four terms of the geometric sequence described in the text?

How do you determine the common ratio of the geometric sequence?

Explain the process of finding a sub 2 in the sequence.

What is the value of a sub 3 and how is it calculated?

Describe how to find the fourth term of the sequence.
